San Luis Low Point 9 valleywater.org San Luis Low Point Improvement Project 10 Valley Water is partnering with the US Bureau of Reclamation to explore utilizing expansion of the Pacheco Reservoir as a potential solution to the San Luis Reservoir Low Point Problem

• San Luis Reservoir is owned by Reclamation and jointly operated with DWR.

• The San Luis Low Point Improvement Project is a being conducted in parallel to the valleywater.org locally led Pacheco Reservoir Expansion Project effort being sponsored by Valley Water and the San Benito County Water District. • Paralleling the two projects provides multiple paths to potential WIIN Act funding.

KJ Scott, Public Information Rep.

Silicon Valley Advanced valleywater.org Water Purification Center Purifying Water for a Sustainable Tomorrow

Uses recycled water and is good for the environment

Provides a drought‐ resistant water supply

Uses state‐of‐the‐art purification processes

Speeds up nature’s process Pre‐Treatment: Intake Pumps and Autostrainer

Intake Pumps –40 PSI Auto‐Strainers Microfiltration

“Outside‐In” membrane filtration

.1 micron pore size, or 3,000x smaller human hair

Organic and inorganic contaminants stay in vessel

Backwash removes contaminants Inter‐process Tank and RO Transfer Pumps

• 225,000 gallon tank, ½ size of Olympic pool

• Backwash water for microfiltration

• Anti‐scaling agent to prevent mineral buildup Reverse Osmosis Feed Pumps

3x450 horsepower pumps

130‐140 psi

$800,000 electricity per year

SVAWPC electricity from Shasta and Oroville Hydropower

Desalination uses RO but would need 1000‐1500 psi Reverse Osmosis

Membrane pores remove substances larger than water molecule

82% permeate/purified

18% concentrate with contaminants • salts • viruses and organic matter • pharmaceuticals • chemicals and pesticides

Bottle water and baby food production Ultraviolet Light Disinfection

• Ultraviolet disinfection for extra layer of safety

• High intensity UV light destroys organic compounds

• 20,000x more efficient than boiling water Finishing Tank and Enhanced Recycled Water

• 2,250,000 gallon tank (10x inter‐process tank)

• Stores advanced purified water before RWWF

• Enhanced recycled water safer for plants and better for industrial cooling systems Future of Advanced Purification & Water Reuse

• Countywide Water Reuse Master Plan

• 10% water reuse, 24,000 AFY

• Long term 45,000 AFY

• Indirect potable reuse

• Direct potable reuse
